Abstract
The utility model elates to an oil/gas-fired atmospheric indirect hot water unit comprising an oil/gas-fired combustor, a unit body, a pipe arranged on the outer shell and communicated with the atmosphere, explosion-proof sheets, a smoke outlet, a water outlet and a water return port, wherein the unit body consists of a boiler, an internal furnace, a reversal chamber, a smoke tube and an outer shell, and a heat exchanger is arranged at the upper part of the boiler. The oil/gas-fired atmospheric indirect hot water unit is characterized in that the unit body adopts the horizontal internal-combustion three-pass integral wet-back structure and takes the shape of a cylinder, the front part and the rear part of the unit body are provided with front and rear smokeboxes, the heat exchanger is arranged at the upper part of the unit, and dismountable seal heads are arranged at both ends of the heat exchanger. In the utility model, the thermal efficiency of the unit is equal to or higher than 92 percent; a heat exchange tube is convenient to be dismounted and replaced; and the unit adopts man-machine dialog intelligent control, thereby achieving simple operation.
Description
Technical field
The utility model relates to a kind of fuel-firing gas-firing normal pressure indirect type hot water unit.
Background technology
Existing fuel-firing gas-firing atmospheric hot-water unit is modal to be that external form is a square, and its unit body is an oval type structure, to carry additionally a square shell in unit body outside in addition, and smoke box, exchanger head add panel mask in addition before and after unit, need take panel earlier apart when causing maintenance, also inconvenient when causing the cost of overhaul; Also increase cost, also be not easy to change.The cigarette system of existing hot water unit mostly is dried back of the body formula structure, this cigarette system process complexity, and heating surface area is little, flue bulk strength deficiency, tube sheet causes weld cracking because of the thermal deformation meeting, and the flue gas sealing difficulty is big, and air leakage coefficient is big, and the thermal efficiency is low; Plug-in panel mask is wanted in outside in front and back smoke box, exchanger head.
The utility model content
The utility model purpose is to provide a kind of thermal efficiency height; Convenient and the integral layout compactness of body maintenance and replacing, rakish a kind of cylinder type fuel-firing gas-firing indirect type atmospheric hot-water unit.
The technical solution of the utility model is: the combustor that comprises fuel oil or combustion gas, by the unit body that boiler, flue, the chamber of strile-bacing, smoke pipe and shell constitute, heat exchanger places upper boiler, be located on the shell with atmosphere siphunculus, burst disk, exhanst gas outlet mutually, delivery port, water return outlet; It is characterized in that described unit body adopts the full wetting back-type structure of horizontal internal combustion three backhauls, is shaped as cylinder type, smoke box before and after before and after the unit body, being provided with, described heat exchanger places unit top, is provided with removable end socket at the heat exchanger two ends.
The two or three time smoke pipe of the full wetting back-type structure of described internal combustion three backhauls adopts threaded flue.
The smoke box door of described front and back smoke box adopts hinge to be connected with the smoke box body.
Described back smoke box is provided with the inspection door of explosion prevention function.
Described flue adopts corrugated internal furnace.
Described unit body is provided with interactive Based Intelligent Control mechanism.
Advantage of the present utility model: (1) unit external form is a round structure, does not have plug-in panel, and smoke box, exchanger head all do not have panel mask before and after unit, need not dismantle panel, and maintenance is convenient, and the sense of unit shape integral is strong, and is beautiful attractive in appearance; (2) the unit body adopts the full wetting back-type structure of horizontal internal combustion three backhauls, and flue adopts corrugated internal furnace to absorb thermal expansion, generatine set heat efficiency 〉=92%; (3) heat exchanger places upper boiler, and two ends are provided with removable end socket, and heat exchanger tube splits out to be changed conveniently; (4) interactive Based Intelligent Control is adopted in unit control, and is simple to operate.
Description of drawings
Accompanying drawing 1 is the general structure schematic diagram.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
Present embodiment comprise fuel oil or combustion gas combustor 1, comprise the combustor of fuel oil or combustion gas, the unit body 2 that constitutes by boiler, flue, the chamber of strile-bacing, smoke pipe and shell, be located at the heat exchanger 3 in the shell, be located on the shell with atmosphere siphunculus 4, burst disk 5, exhanst gas outlet 6 mutually, delivery port 7, water return outlet 8.The unit body of present embodiment adopts the full wetting back-type structure of horizontal internal combustion three backhauls, is shaped as cylinder type, and the two or three time smoke pipe of the full wetting back-type structure of its internal combustion three backhauls adopts threaded flue.Smoke box 9 before and after being provided with before and after the unit body, its smoke box door adopts hinge to be connected with the smoke box body.Be provided with removable end socket 10 at the heat exchanger two ends.Back smoke box is provided with the inspection door 11 of explosion prevention function.Interactive Computerized intelligent control is adopted in unit control, and is simple to operate.
Fuel sprays from combustor, and in the flue internal combustion, the thermal-flame of generation is discharged from exhanst gas outlet 6 after the unit heat absorption.High temperature matchmaker water in the unit body 2 is through the copper pipe heat exchange of heat exchanger 3, and heat is passed to recirculated water in the copper pipe, is heated again after the high temperature matchmaker water cooling, moves in circles.Recirculated water enters from water return outlet 9, and the heating back picks out from delivery port 8.Recirculated water can be used as air conditioning hot or health hot water.
